Hi, welcome to the forums!
If you haven't already, please read Understanding Your FICO ® Score and Credit Scoring 101 (at least the first post.)
These will give you the background knowledge you need to understand what you read here on the forums.
6 - 8 cards is probably a bit much, right off the bat, but it's not unreasonable as an eventual goal. We used to send everyone new to the US over to Bank of America (BofA) and Capital One (Cap1) as being emigrant-friendly, but it's hard to tell what anyone is doing these days. I'd look into a local credit union if you have one. They work differently from banks, and they're much more willing to help newcomers. Traditionally they had narrow membership categories (employee groups and so forth), but most have broadened greatly. In some areas, the banks have successfully blocked CU's from expansion (Chicago, NYC), and you might have to fall back on BofA.
Don't know about those specific cards.
An initial credit score (once you have one) will probably be in the mid-600's.
You might try looking for old posts by wmarat, another member who had to start his credit history from scratch. Click "user search" above, type in his name and enter, and choose "find all posts by this member" (might not be the exact phrase.) Once his posts come up, click on the Date heading to get his oldest posts first. As I recall, he had some frustrating times, lol, but he built his credit very successfully. It's better than mine is, that's for sure!
